    • 专利摘要:
    A known antibiotic, SF-1293 substance and salts thereof have now been found to exhibit high herbicidal effects against a wide variety of herbaceous and woody plants, but they are non-phytotoxic particularly to a useful woody plant, Chamaecyparis obtusa. The herbicidal effects of these SF-1293 substances can be synergistically enhanced by applying in combination with herbicides selected from Linuron, Monolinuron, Monuron and Diuron each known as herbicides of urea derivative class.

    专利说明:

    This invention relates to chemical methods for controlling weeds and unwanted vegetation by treating it or the soil on which it grows with herbicides.
    Known methods of combating unwanted vegetation, based on the use of herbicides from the group of aryloxy acetic acids and their derivatives. These include, for example, a method based on the use of 2,4-dichlorophenoxyacetic acid (2,4-D) and various RH derivatives.
    However, the known methods of this type are not sufficiently effective in relation to certain types of weed and non-P - CHaCHOCH-CNHT-CHIIchI
     CH3 with a mass ratio of compounds (I) and (II) equal to (1-4): 1 and with a total amount of 1.5-3 kg / ha. The organophosphorus compound (II) and its sodium salt are known as herbicides 2, However, they are also not sufficiently effective for these types of weeds. The combined use of a mixture of two known herbicides (1) and (II) leads to the achievement of a synergistic effect and allows you to more successfully deal with weeds and undesirable vegetation. This mixture of herbicides can be used in conventional formulations, including such as solutions, powders, pastes, granules, emulsions, etc. They are prepared by known methods. Example. Experimental weed plants under greenhouse conditions before a certain growth stage and treat them with aqueous solutions of compounds (I) and (II) individually and mixed with each other. 21 days after the treatment, the degree of damage to the plants was visually estimated, expressed in points and percentages, in the following way: Percentages
    vegetation, such as Rumex obtusifolius (dull sorrel) and Loysia Japonica.
    The aim of the invention is to increase the efficiency of a method for controlling undesirable vegetation based on the use of 2,4-D.
    This goal is achieved by the proposed method by sharing sodium salt 2, 4-D of the formula

    sn. 5100 After 3 months thereafter, a reduction in the secondary growth rate of plants is assessed to suppress secondary waste. For this purpose, the following labels are used: (-) - absence of secondary growth; (±) - significant suppression of secondary growth; (+) - marked, suppression of secondary growth; (+4) - moderate suppression of secondary growth, (() - no suppression of secondary growth. The synergistic effect is calculated using the natural Colby formula .Y-Ll. 100 X - degree of plant damage (%) when using herbicide (1) in the amount P (kg / ha);

    degree of plant damage (%) when using herbicide (II) in the amount of q (kg / ha),

    and (ii) higher than calculated by formula (E), then there is a synergistic effect.
    Herbicidal effect of a mixture of herbicides (I) and (II) and the effect of synergism 5 when herbicides (I) and (II) are used together are presented in Tables 1 and 2, respectively,
    The results of the experiments indicate the presence of synergism in the joint use of herbicides (I) and (11) and the high efficiency of the method according to the invention.
